About Plain
Sidekick got skills and MCP; now Plain is clearing the path to move your history in.
Plain's recent releases built Sidekick from an in-thread helper into an operator that uses workspace skills and connects to any MCP server, with workflows becoming the trigger layer for that agent work. The newest entry moves to the other end of the funnel: custom importers pull past conversations in from any tool, including in-house systems, with no built-in importer required.
